NON-REFILLABLE BOTTLE.

To all whom it may concern:

Be it known that I, CONRAD JURKovIoH, a V

to prevent the partial or complete refilling of a bottle.

Further objects of the invention are to provide a non-refillable bottle which is simple in its construction and arrangement, strong, durable, efficient and convenient in its use, readily set up and comparatively in expensive to manufacture.

\Vith the foregoing and other objects in view the invention consists of a novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in' the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claim hereunto appended. In the drawings wherein like reference characters denote corresponding parts throughout the several views, Figure 1 is a vertical sectional view of a bottle, broken away, showing the formation of a bottle neck of a non-reflllable bottle in accordance with this invention. Fig. 2 is a vertical sectional view, broken away, of a non-refillable bottle in accordance with this invention. Fig. 3 is a top plan view of a val ular element employed closing the neck. Fig. 4 is a vertical sectional view of a valvular element. Fig. 5 is a plan view of the lower end of the valvular element.

Referring to the drawings in detail 6 denotes a body portion of bottle and 7 the neck in which is formed a throat 8. The wall 9 of the throat 8, is formed with an annular flange 10 intermediate the ends of the throat. The said flange 10 is adapted to suspend within the throat a valvular element to prevent the partial refilling or com- Specification of Letters Patent. P t te Ma 14., 1916; Application filed September 8,1914. Serial No. 860,755. I v l plete refilling of the body portion 6 of the bottle. The valvular element includes a hollow annular member'll which decreases 1n diameter from its lower-toward its upper end and is formed. at its lower end with an inwardly extending annular flange 12,

which constitutes a seat for a pair of flap valves 13, 14:, which arepivoted upon a pin '16, carried at the lower end of the member l l.

The member 11 at its top is provided with a cap piece 17, which is formed with a pair of annular shoulders 18, 19, one arranged above the other.

Secured to the periphery of the member 11, is a pair of holding springs 20, having their upper ends provided with inwardly projecting extensions 21. The springs 20 are curved in the direction of their length.

When the valvular element is positioned in the throat 8 of the bottle neck 7, the shoulder 19 is seatedupon the flange 10, and the shoulder 18, is flush with the lower face of the flange 10. The projections 21 of the springs 20 bear against the lower face of the flange 10, and also against the shoulder 18. Under such conditions the valvular element is maintained in position, that is to say, it is prevented from being forced in- ,war'dly,and from being pulled outwardly.

The cap piece 17 is ,provided throughout with openings 22 to permit of the discharge ,of the contents of the bottle, when the valves 17, 14: are shifted off their seats, whenthe bottle is tilted for the purpose of pouring contents therefrom.

lVhat I claim is The combination with a bottle neck formed with an annular flange in the throat thereof, of a valve consisting of a perforated cap member adapted to seat upon said flange, a circumferential flange formed integral with one face of said cap and coextensive in circumference and thickness with the inner edge of said flange, an annular depending member formed integral with said circumferential flange near the inner face thereof, an inwardly extending annular flange formed integral with the lower end of said annular depending member, a bearing interposed transversely of said last-mentioned flange, oppositely dis posed semi-circular valve plates pivoted upon saidbearing, and retaining springs secured at their lower ends upon the lower In testimony whereof I aflix my signature portion of said depending member and in the presence of two witnesses. formed with inward extensions on the upper T ends engaging the bottom face of said cir- V GOLRAD JURKOVICH cumferential flange, and adapted to engage WVitnesses:
